Need a really big laptop battery!

How can I get a really really big rechargable "laptop battery"? Thinking 12-24 hours worth of charge on a laptop that can drain a high-cap battery in 1 - 1.5 hours.

I thought the best way to go would be to grab a car battery and an inverter, but I've read that car batteries are excellent at high-output rates but don't actually have a large capacity. Most estimates say the car battery would last about an hour.
A vehicle would be nearby; intended use is camping (and a lot of travel but not a fixed location). I've heard that some of the solar cells are getting good enough to power a laptop, but in the middle of the night I need the power to be available for hours on end, so what would the solar cells store into?
Is there some sort of big beefy computer-centric battery pack I can buy, that doesn't rely on a wall outlet?
Bonus points if it can also be recharged while my vehicle is in motion.
